Interpreting Preferences in an Altruistic Choice Model
Two individuals, Sam and Pat, are each given a fixed sum of money to allocate between themselves and another person. Their choices are modeled on a graph where the horizontal axis represents the amount of money they keep, and the vertical axis represents the amount they give away. Both face the identical straight-line 'feasible frontier' representing all possible allocations. However, the 'indifference curves' representing Sam's satisfaction are much flatter than the indifference curves representing Pat's satisfaction. Analyze what this difference in the shape of their indifference curves reveals about their underlying preferences and predict who is likely to give more money away. Justify your prediction using the logic of the graphical model.

Zoë's Utility Function for Altruistic Choice
An individual must decide how to allocate a fixed sum of money between themself and another person. The accompanying graph illustrates this choice. The straight diagonal line represents all possible allocations (the feasible frontier). The curved lines are the individual's indifference curves, where curves further from the origin represent higher levels of personal satisfaction. Which point represents the individual's optimal allocation, and why?
Analyzing an Altruistic Decision
Analysis of a Suboptimal Altruistic Choice
Consider a graphical model where an individual is deciding how to allocate a fixed sum of money between themself and another person. The straight line represents all possible allocations, and the curved lines represent the individual's levels of satisfaction (with curves further from the origin indicating higher satisfaction). If a specific allocation point lies on the straight line but is intersected by a satisfaction curve (rather than being just tangent to it), this point represents the best possible choice for the individual.
Interpreting Preferences in an Altruistic Choice Model
In a graphical model representing an individual's decision on how to allocate a fixed sum of money between themself and another person, match each graphical component to its correct interpretation.
In a graphical model of altruistic choice, the optimal allocation of a fixed sum of money between oneself and another person occurs at the point of tangency between the feasible frontier and an indifference curve. At this specific point, the individual's marginal rate of substitution (the rate at which they are willing to trade their own money for the other person's) is exactly ______ to the marginal rate of transformation (the rate at which they can trade their own money for the other person's).
You are tasked with creating a graphical model to determine the optimal way for an individual to allocate a fixed sum of money between themself and another person, based on their personal preferences. Arrange the following steps in the correct logical order to construct this model and find the solution.
The provided graph illustrates how an individual decides to split a £200 windfall between themself (horizontal axis) and a friend (vertical axis). The straight diagonal line shows all possible allocations. The curved lines represent the individual's satisfaction levels, with curves further from the origin representing higher satisfaction. Initially, the individual's optimal choice is at Point A (£140 for themself, £60 for their friend). Suppose the individual's attitude changes, and they become substantially more altruistic, valuing their friend's gain more than they did before. Which of the following points is the most plausible new optimal choice?
